Answer:
<h2>
![\cos(A) = \frac{2 \sqrt{6} }{7}](https://tex.z-dn.net/?f=%20%5Ccos%28A%29%20%20%3D%20%20%5Cfrac%7B2%20%5Csqrt%7B6%7D%20%7D%7B7%7D%20)
</h2>
Step-by-step explanation:
Since we are finding cos A we have
<h3>
![\cos(A) = \frac{AC}{AB}](https://tex.z-dn.net/?f=%20%5Ccos%28A%29%20%20%3D%20%20%5Cfrac%7BAC%7D%7BAB%7D%20)
</h3>
From the question
AC = √96
AB = 14
Substitute the values into the above formula
That's
<h3>
![\cos(A) = \frac{ \sqrt{96} }{14}](https://tex.z-dn.net/?f=%20%5Ccos%28A%29%20%20%3D%20%20%5Cfrac%7B%20%5Csqrt%7B96%7D%20%7D%7B14%7D%20)
</h3>
We have the final answer as
<h3>
![\cos(A) = \frac{2 \sqrt{6} }{7}](https://tex.z-dn.net/?f=%20%5Ccos%28A%29%20%20%3D%20%20%5Cfrac%7B2%20%5Csqrt%7B6%7D%20%7D%7B7%7D%20)
</h3>
Hope this helps you
4x - 6y = -26
-2x + 3y = 13 Multiply this by 2:-
-4x + 6y = 26 Add the first equation to this one. We get:-
0 + 0 = 0
Both equations graph is the same lien.

Based on the rules of statistics</span>
68% of the data falls within 1 standard deviation of the mean
95% of the data falls within 2 standard deviation of the mean
99% of the data falls within 3 standard deviation of the mean
20 falls between the range of -56 to 56 (from the given 95%)
Hence we accept the null hypothesis; else, if the mean falls outside the
range, we reject the null hypothesis.

Answer:
3
Step-by-step explanation:
You want the greatest of three consecutive odd integers that have a sum of 3.
<h3>Average</h3>
The average of the integers is their sum divided by their number:
average = 3/3 = 1
This is the value of the middle of the three integers, so they are ...
-1, 1, 3
The greatest of the three is 3.
